DRIVING MECHANISM.

To all whom it may concern:

Be it known that I, JUs'rUs FEYER, a subject of the German Emperor, andresiding at Barman, Rhenish Prussia, Germany, have invented certain newand useful Improvements in Driving Mechanism, of which the following isa full and clear specification.

The object of my invention is to provide an electric motor for drivinglooms and the like machines and it consists in the arrange ment and useof constructions for journaling the motor so that the same may not findsolely a resistance in the machine which should be driven but also inanother element forming a force accumulator in order that a greatequality in the motion of the machine may be obtained.

With the above and other objects in view my invention consists in thenovel construction and arrangement of parts illustrated in theaccompanying drawings, in which Figure 1 is a side view of the completedriving device for a loom, Fig. 2 is a similar view of a modifiedconstruction, Figs. 3 and 4 are modified details of construction of saiddevice and Fig. 5 another modification from which Fig. 6 is a detail.Fig. 1 illustrates a detailed view of the coil spring.

Like letters of reference indicate like parts in the drawings.

Referring to Fig. 1 the reference numeral 1 is an electric motor of anysuitable construction which is fastened to a holder or arm 2 that isloosely fitted on a shaft 3 which shaft is at the same time the drivingshaft of a loom or other working machine with irregular working speedand force. On said shaft 3 is keyed a gear wheel 4 which is in mesh witha gear 5 on the motor shaft 6. The whole device is mounted on a standard7. On one end of the shaft 10 there is a head 12 which is pivotallyconnected to the motor 1. A sleeve 9 carrying the collar 8 is rotatablymounted on the shaft 10. The said collar, operates in the groove 7' ofthe standard 7, which collar forms a guide for the shaft 10. On the freeend of the shaft 10 is mounted a washer 11 which is held thereon by thenut 15, the said washer forming a stop for one end of the coil spr ng13; the opposite end of the sprmg engaglng the collar 8 for restrictingmovementthereof.

When starting the motor by feeding 1t with electric power the same willturn around its suspension point 3 until the resistance of the 100m andthe spring 1s in ac- Specification of Letters Patent.

cordance with the turning moment of the motor which is pending on theshaft 3. If the resistance of the loom is diminished the motor is turnedin contrary direction by means of the spring, the nut 15 being provldedfor regulating the tension of the same. It may be pointed out, that thespring may have any convenient form or shape, so for lnstance it may beshaped or coiled of square-shaped wire or made conically as shown inFig. 1 In the latter case it may better resist the forces developing inthe loom.

In Figs. 2, 3 and 4 a modification of my invention is illustrated. Inthis construction to the shaft 3 is keyed a box 16 extending in an arm 2with which is connected the motor 1 the shaft 6 of which carries againthe gear 5 being in mesh with the gear 4 that is loosely mounted onshaft 3. The said box 16 is surrounded by a brake band 17 extend ing inthe pieces 18 that may be screwed together by a set screw 19 allowingthus to regulate the action of the brake. The box 16 forms part of anarm 2 on which is fastened a rod 20 in a suitable manner which carries aweight 21 as will be seen and as will be understood from the foregoingthe motor may pend also on said shaft 3 and the weight in combinationwith the brake may regulate the irregular working forces in the loom orother machine, which in this case is driven by the gear 4. To improvethe action of the arrangement of parts, I insert in the interior of thebox 16 spirally wound springs 22 one end of which is in connection withthe inner wall of the box and the other is inserted in a slot 23 of theshaft 3. A lid 24 fastened to the box with screws 24 protects thesprings as shown. It may be mentioned, that the weight may be alsoarranged to slip to and fro on its rod for the purpose of regulating theworking action of the parts.

In Figs. 5 and 6 another modification of my machine is illustrated. Themotor 1 is connected with a box 26 seated on shaft 3 by means of a screw27 and corresponding nuts and it may be lowered or raised by said screwin order to conveniently change the gears 4 and 5. The box is closed onboth sides by lids 28. Within said box or casing 26 are located twoboxes 29, and 30 having lateral segmental recesses 31, and 32 whichproject through the said lids 28 and with said recesses engage the setrings 33, 34

the casing 26 vand motor 1 are-rotatably mounted. Ball bearings notshown in, the drawing may be used to support the oscillating movement ofthe motor. In the casing 26 are arranged coil springs 37, one end ofeach of said coil springs being fixedto the casing, and the oppositeends of the springs being secured to the. boxes 29 and 3,0, the; saidsprings being so arranged that when the motor is in operation, the saidsprings expand.- By making the'springs of thicker or thinner wire or byinserting a corresponding number of springs the resistance of the loommay be accordingly regulated.
